## electric field near two wires

I'm not asking for the solutions, I just need to know what methods to use.

1. The problem statement, all variables and given/known data

3. The attempt at a solution

I got this equation using this method

but I don't know how to apply it to the questions. I think I need to be using unit vector notation as well?

Also, it asks for the total field, but don't both wires cancel each other out?

 If By ρ you mean λ ... What do you think R is in your eqn? Using that you can easily find Electric field due to 2 wires independently and also using some trigo you can also find the directions (directions are radially outwards from long uniformly charged wires) Then just sum the individual E using vector additions law.
